PHILIP T. DODGE, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGEN- THALER LIN OTYPE COMPANY, A CORPORATION OF NEW YORK.

LlNOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 792,504, dated June 13, 1905.

Application filed March 17, 1905. Serial No. 250,624.

To aZZ whom it may concern.-

Be it known that I, PHILIP T. DODGE, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention has reference to linotype-machines and kindred typographic machines wherein type matrices or dies are stored in a channeled magazine and delivered therefrom one at a time by means of escapement devices, and is intended more particularly for use in the commercial Mergenthaler linotype-machine of the general organization represented in Letters Patent No. 436,532 of the United States. In this class of machines it is sometimes desirable to release and discharge instantly all of the contained matrices.

My invention consists in so mounting the series of escapements that they may be instantly retracted or drawn back from the operative position beyond the path of the matrices, so as to release the latter and permit them to pass from the magazine without interruption.

The invention may be embodied in various forms and the details modified at will, provided only the escapements are movable instantly to and from their operative position.

Figure 1 is a side elevation of the lower end of a linotype-machine and the escapement devices therein, portions being shown in vertical section on the line 1 l of Fig. 3 with the escapements in operative position. Fig. 2 is a similar view with the escapements retracted to release the matrices. Fig. 3 is a bottom view looking in the direction of the arrow 3, Fig. 1.

Referring to the drawings, A represents the usual inclined magazine, consisting of parallel plates a a,-secured to separating plates or bars a. and provided in their inner faces with grooves or channels to receive and guide the edges of the matrices B. The magazine as a whole is secured, as usual, to an underlying base-frame a? or other suitable support.

C represents one of the ordinary escapement devices, consisting of a centrally-pivoted lever, provided at the opposite ends with two pawls or dogs, which are arranged to project upward alternately through the bottom of the magazine in order to engage and disengage the successive matrices that they may be delivered one at a time from the magazine. Each escapement is urged in one direction by a spring 0 and in the opposite direction by a reed or bar 0 connected with a finger-key mechanism and actuating-spring, as usual.

Heretofore the escapement devices have been mounted in a bar or support rigidly attached to the under side of the magazine and designedto remain permanently in place, so that the matrices could be delivered from the lower end of the magazine only by actuating the escapements and releasing them one at a time.

I depart from the ordinary construction by mounting the entire series of escapements in a supporting bar or frame D, connected to the magazine by horizontal pivots (Z in such manner that when required the bar may be swung downward from the operative position (shown in Fig. 1) to the position shown in Fig. 2, thereby lowering all of the escapement-clogs beyond the matrix-path, so that the matrices contained in the magazine may escape freely therefrom.

The frame D is preferably constructed as shown to guide the upper ends of the dogs or pawls in order to keep them in the proper relation to each other and to the lever when they are lowered from the operative position.

The swinging escapement-bar is provided at its ends with arms (Z, arranged to swing upward at the sides of the magazine and provided with spring-actuated pins (Z arranged to enter seats at the side of the magazine to lock the bar and escapements up in their operative positions.

The essence of the invention lies in mounting the escapement-support D, whatever its form, in such manner that it may be moved to carry the escapements beyond their operative positions, and it is manifest that the bar may be supported by pivotal or hinged connections in any form equivalent to those herein shown and that in place of the arms cl any other suitable locking or fastening device may be employed to hold the bar rigidly in position.

It will be observed that in the form shown the bottom plate is continuous, except as to the holes through which the dogs or pawls ascend. The escapement-supporting bar D is hinged to seat itself firmly against the under side of the magazine-plate.

While I have shown my device in connection with escapements located on the under side of the magazine, it is obvious that the same or a similar construction may be employed when the esoapements are located on the upper side of the magazine, this location being common in the art.

Having described my invention, what I claim is- 1. In a typographic machine, the combination of a magazine, escapements controlling the delivery of matrices therefrom, and means whereby the escapements may be thrown into or out of their operative position.

2. In a typographic machine, the combination of a magazine, a series of escapements controlling the delivery of matrices therefrom, a support for the eseapements movable at will to permit the withdrawal of the escapements from their field of action, and means for securing said support in operative position.

3. In a typographic machine, the combination of a magazine, a series of escapements to control the discharge of the matrices, a hinged support for said escapements, and means for locking the support in operative position and for releasing the same at will.

4:. In a typographic machine, the combination of the channeled magazine, the escapements 0, the swinging support D, wherein the escapements are mounted, the arms d, and locking devices for holding them in position.

5. In a typographic machine, a channeled magazine, an escapement controlling the delivery of matrices from one of its channels, and means whereby the esoapement may be withdrawn from and restored to its operative position, substantially as described.

In testimony whereof I hereunto set my hand, this 14th day of March, 1905, in the presence of two attesting witnesses.
